Abstract: The present disclosure discloses a method and device for indicating a network mode. The method comprises detecting a format of a value of a Public Land Mobile Network IDentity (PLMN-ID) in a system information block; and determining, when the value of the PLMN-ID is a value indicated according to a first preset format, the indicated value as information indicating that a network mode is a Neutral Host (NH) mode, wherein the first preset format is a format different from a second preset format which is a format of the PLMN-ID in an Evolved Packet Core (EPC) connected mode. The present disclosure solves the technical problem of the increase in protocol complexity caused by different message formats since the EPC connected network mode and the NH network mode use the IDs of completely different types and numbers.

Abstract: The present disclosure discloses a transmission processing method and device. The transmission processing method includes: performing uplink scheduling for a User Equipment (UE) in accordance with an uplink scheduling criterion, and determining whether to apply puncturing in accordance with an uplink scheduling result and/or determining whether to instruct the UE to apply the puncturing via signaling in accordance with the uplink scheduling performed for the UE. The uplink scheduling criterion is preset and is for limiting the uplink scheduled UE to reduce a number of puncturing operations. In the prior art, an uplink scheduled UE that is transmitting data needs to be instructed to apply puncturing in a fixed position of a subframe whenever a new uplink scheduled UE appears in a wireless communication system, resulting in a technical problem of a low transmission rate, which is solved in the present disclosure.

Abstract: The present invention discloses a method, a terminal and a network-side access device for reporting PLMN. The method includes: receiving, by a terminal, a PLMN identifier list sent by a network-side access device; selecting, by the terminal, a first PLMN identifier from the PLMN identifier list, so as to connect with the network-side access device; and after the terminal is connected with the network-side access device, labeling, by the terminal, a second PLMN identifier preset in the terminal as a selected PLMN identifier and reporting the selected PLMN identifier to the network-side access device, wherein the first PLMN identifier is different from the second PLMN identifier. The present invention solves the technical problem of limitation of operation on PLMN reporting due to adopting the conventional PLMN reporting manner.
